Nearly there with the re build of tr7 convertible 1980.I have a problem with the N/S headlamp.O/S going up and down fine.N/S not lifting but lights working.Swapped relays and its not those.Taken the motor out and wired it to the O/S wiring and it is working.It therefore is something to do with the Ns wiring or something in the loom which is not allowing power through to unit.Checked the fuses and its not that.Is there something else specific to each side that could be faulty.
regards.Steve.
